Reduced nephron number and glomerulomegaly in Australian Aborigines: A group at high risk for renal disease and hypertension

Aborigines in remote areas of Australia have much higher rates of renal disease, as well as hypertension and cardiovascular disease, than non-Aboriginal Australians. We compared kidney findings in Aboriginal and non-Aboriginal people in one remote region. Glomerular number and mean glomerular volume were estimated with the disector/fractionator combination in the right kidney of 19 Aborigines and 24 non-Aboriginal people undergoing forensic autopsy for sudden or unexpected death in the Top End of the Northern Territory. Aborigines had 30% fewer glomeruli than non-Aborigines-202000 fewer glomeruli per kidney, or an estimated 404000 fewer per person (P=0.036). Their mean glomerular volume was 27% larger (P=0.016). Glomerular number was significantly correlated with adult height, inferring a relationship with birthweight, which, on average, is much lower in Aboriginal than non-Aboriginal people. Aboriginal people with a history of hypertension had 30% fewer glomeruli than those without-250000 fewer per kidney (P=0.03), or 500000 fewer per person, and their mean glomerular volume was about 25% larger. The lower nephron number in Aboriginal people is compatible with their susceptibility to renal failure. The additional nephron deficit associated with hypertension is compatible with other reports. Lower nephron numbers are probably due in part to reduced nephron endowment, which is related to a suboptimal intrauterine environment. Compensatory glomerular hypertrophy in people with fewer nephrons, while minimizing loss of total filtering surface area, might be exacerbating nephron loss. Optimization of fetal growth should ultimately reduce the florid epidemic of renal disease, hypertension, and cardiovascular disease.

The Populist Message of Australian Country Music

Australian country music is influenced by American country music and Australian bush ballads. This music idealises genuine true blue inhabitants of an idealised rural heartland and fuses nationalism with agrarian mythology. The lyrics of a number of country songs contain a populist political message, which is frequently nationalistic but is a form of nationalism.

Tradition, myth and the dilemma of Australian foreign policy

For a middle power with a relatively short history of framing a self determined foreign policy, Australia has actively sought to engage with both its immediate region and the wider world. Elite agreement on this external orientation, however, has by no means entailed consensus on what this orientation might involve in terms of policy. Consequently, two, often conflicting, traditions and their associated myths have informed Australian foreign policy-making. The most enduring tradition shaping foreign policy views Australia as a somewhat isolated bastion of Western civilisation. In this mode Australia's myth is pragmatic, but uncertain and sees Asia as both an opportunity and a potential threat which requires the support and counsel of culturally similar external powers engaged in the region to ensure stability. Against this, an alternative and historically later tradition crafted a foreign policy that advanced Australian independence through engagement with a seemingly monolithic and increasingly prosperous Asia. This paper explores the evolution and limitations of these foreign policy traditions and the myths that sustain them. It further considers what features of these traditions continue to have resonance in a region that has become more fluid and heterogeneous than it was during the Cold War and which requires a foreign policy flexibility that can address this complex and strategically uncertain environment.

Notes on the history of the mobile phone in Australia

The first automatic mobile phone service was launched in Australia in 1981, with the first cellular mobile service following in 1987. In 2003 there were over 14.5 million mobile phone subscribers, and the technology had become central to everyday life and culture. Despite the significance of mobile phones, little has been written about their Australian histories. This paper offers some notes on the history of mobile telecommunications in Australia. As well as reviewing the development of the mobile phone in Australia, it looks at the cultural representation of this technology.

Women from the Union of Australian Women with banner during Aldermaston Peace march in 1964

Women from the Union of Australian Women with banner during Aldermaston Peace march, Sunday, April 5th 1964. The Aldermaston march covered the distance between Ipswich and Brisbane, Australia, walked in relays covering approximately two miles each. Most relay sections were sponsored by one or more individual organisations. The Union of Australian Women is a national organisation that was formed in 1950. Its aim is to work for the status and wellbeing of women across the world. It has been involved in a wide variety of campaigns that concern women. The Union of Australian Women networks with other women's community and union groups on such issues.
